This post is part of a series on making and using the Gingery Foundry.

I’ve made several posts so far about putting together a Gingery foundry setup: flasks, molding sand, and air blast control. The next thing I needed to have a working foundry was the actual foundry furnace.

The furnace is contained in a 5 gallon steel bucket. Two 8” plywood disks were cut out, and wrapped in sheet metal to create a form for the interior of the furnace. I drilled a couple holes in the bucket for drainage and tuere outlets.

This post is part of a series on making and using the Gingery Foundry.

One of the most critical elements of the solid fuel foundry is the air supply. A constant blast of air is what lets the furnace get hot enough to melt metal. Gingery recommends using a bonnet hair dryer to feed the furnace blast, but since I don’t have one I’ll be using the the blower output from a shop vac.

Unfortunately, using a shop vac for a furnace this size is tremendously overpowered. Running the air at full blast for any length of time would melt my furnace down into slag and glass. I need some way to control how much air is actually being directed into the furnace.
